We analyzed the dynamic characteristics of cantilever biosensor for the detection of disease using antibody-antigen reaction. We suggested a design guide to detect the mass of protein. The length of cantilever is the major factor among shape dimensions to affect the mass resolution and it should get smaller for the better accuracy. However this mass detection model does not explain all the experimental results, therefore we adopted the beam equation with tension. Adding the effect of tension on the shift of resonance frequency, the experimental results could be explained.
